Battle Cats Wiki

No Plan A (Deadly) is an Advent Stage appearing on the 7th, 8th, 21st, and 22nd of every month. When clearing the stage, there is a chance to unlock Catway. This is a No Continues stage. In The Battle Cats Unite, it is a permanent stage that can be unlocked once clearing Floor 10 in the Heavenly Tower.



Although Cruel Angel Clionel isn't a hard enemy by herself, the nasty angel peons can easily turn the tables if left unchecked. Common approaches tend to employ unit with enough speed or durability to get within Clionel's blindspot, and take the fight from there.

A typical strategy would involve using fast units like Awakened Bahamut Cat to deal as much damage to her as possible before more peons can spawn, ideally destroying her so the other threats become manageable. A level 30+ Artist Cat is recommended to have (optimally with True Form and Talents), as well as Ultra Souls units so Clionel can be stalled. Ushiwakamaru can even solo this stage if spammed with the help of Research Combos.

If you have a Level 50 & fully talented Ramen Cat, this stage becomes a cakewalk.

Cat's Gift can be somewhat helpful, as it can infiltrate Clionel's blind spot and freeze Clionel, allowing for better timing of your other units. However, it is only a 30% activation chance, and thus is unreliable; although harder to obtain, a fully Speed-Up Talented Juliet the Maiko will provide better support, having a full second longer freeze and a 10% higher chance of Freeze activation. Talented Sanzo Cat can be helpful against the Angelic Gories in this stage, provided you lure the peons closer in order to kill them.

Recommended Units[]

  • Awakened Bahamut - Bahamut, being a fast rusher with massive DPS at the cost of range and health, is the essence of many strategies as he'll be their main damage source, whether against Clionel or the peons.
  • Ramen - Since most threats in this stage are Angels, Ramen's singular knockback, high health and resistance against them makes it more than ideal for this particular showdown.
  • Manic Lion/Bullet Train - As supplementary rushers, Manic Lion and Bullet Train can both take advanatge of their extreme speed to pin Clionel and inflict extra damage. Bullet Train even backs this up with the Extra Money ability, which, combined with its full backswing and knockback effects from Trolly Blogger/Sleipnir can either do serious damage or provide a boost to your economy.
  • Green Shell - Green Shell's massive health for its low cost, high speed, singular knockback and immunity to Knockback/Slow greatly aids rush strategies. It can stall Sleipnir, Clionel and Trolly Blogger while buying rushers much more time to inflict damage. However, Green Shell has a long cooldown and comes from a very difficult advent stage, so you'll have to balance your priorities.
  • Can Can - Can Can is a powerful single-target attacker with huge damage at close range. Primarily useful against Angelic Gories, augments with Extra Money and Move Speed Up allows it to get even more value for its low cost.

Recommended Ubers[]

  • Kalisa: Kalisa is a fast rusher with massive damage to Angels and full backswing attacks. She can fit inside Cruel Angel Clionel's blind spot and nuke the Angelic Gories in no time flat. Be aware that Sleipnir can either knock her back into Clionel's effective range or stunlock her to death.
  • Guardian Gamereon or Thunder God Zeus: Both can tank an ungodly amount of punishment and can help clear out the Angelic Gories and Trolly Bloggers. They can help give you breathing room and even dish out some damage on their own, but be careful of knockbacks from the Sleipnir and Bloggers.
  • Kasa Jizo: Fast, spammable and deals extreme damage to angels. He can easily keep the Angelic Gories at bay and shoot down Clionel if he makes into her blind spot.
  • Ushiwakamaru - The zenith of Angelic destruction, Ushiwakamaru's main highlights include its Resistance/Insane Damage ability against Angels. Both forms can be used here to great effect, but they aren't perfect - The first form can solo the stage only with research combos, and the latter requires considerable support to actually get a hit on, as it isn't immune to Weaken/Slow.
  • The One-Hit Wonders: High range, strong against angels with immunity to slow and weaken. Ideal for taking on any enemy, though Sleipnir's knockback may pester them.
  • Sanada Yukimura: Yukimura can act as a second Awakened Bahamut and assist with rushing down Sleipnir and Clionel.
  • Juvens: Excellent health, resistance to angels combined with dodge allows him to stand his ground, even dodging Sleipnir's pushing attacks often. Offers top-level protection while delivering massive DPS and having a quick enough recharge to keep up if he is destroyed.
  • Thunder Jack: Excellent health, his knockback can stunlock Clionel, is fast enough to enter her blindspot, can hold its own against her for a decent while, and is cheap and has quite the fast recharge.

Strategy 1[]

Lineup: Macho Leg Cat 20+40, Awakened Bahamut Cat 30, Artist Cat 36+, Lion Cat 20+40, Crazed Giraffe Cat 20

Cannon: Default Cat Cannon


  • Ramen Cat can be used in a lower level than Artist Cat.
  • The open slots are for Unit Defense UP Combos and other units that may be helpful.
  • Alternatively, you can include units such as Baseball Mask β or certain Ultra Souls in place of Macho Leg or some Combo cats (as long as you can still apply a good Combo/set of Combos).
  • Don't bring Rich Cat and Sniper the Cat. They can throw off timing.

Battle: Start off by spawning a Crazed Giraffe as soon as you can. (If your timing is even a second off, he can die.) Then upgrade your Worker Cat to 2, and spawn Lion. Make sure to upgrade your Worker Cat to level 5. Don't spawn anything for a while. Wait for the first Angelic Gory to get close to the Cat Base. Then spawn Artist and the other three attackers, as well as A. Bahamut.

Don't let Bahamut die early. He can take out the Angelic Gories and the first Angelic Sleipnir. After the first Sleipnir is knocked back, use the Cat Cannon to stop Clionel's attack. Then kill Sleipnir and proceed to Cruel Angel Clionel. If you do it perfectly, Cruel Angel Clionel should be knocked back twice, and the 2nd Sleipnir should be knocked back once.

Start by not doing anything until you can spawn a second Awakened Bahamut. Just stall them. Let the Angel Gories get close to your base, and save the Cat Cannon. Use A. Bahamut 2 to take out the Angelic Gories and finish the second Sleipnir. Spam the attackers, and you should eventually bring down the Cruel Angel Clionel. More Sleipnir will spawn with more groups of Angelic Gory. Awakened Bahamut can take care of them and finish off the level.

Strategy 2[]

Beginning: Once the battle starts, spawn a Manic Lion Cat, then another when you can and get your Worker Cat's level up to 6. When a Trolly Blogger reaches the 1/4 mark, send in Manic Macho Legs. He should force the Angelic Sleipnir to attack it, which will help later. When the Angelic Gory kills your Legs and nearly reaches your base, in quick succession send in Awakened Bahamut, Manic Lion Cat and Ramen. Continue spamming Ramen and Manic Lion. Angelic Sleipnir should be knocked back now. Use the Cat Cannon to interrupt the boss' attack sequence. Spam Ramen, Manic Lion and Fishman, as well as Hyper Mr. if you have him talented. You'll want to knock back Clionel thrice.

Second Sleipnir Phase: If Awakened Bahamut is still alive, he may able to knock back the Sleipnir once before dying. He could knock back some of the Angelic Gories, though this is not mandatory. MAKE SURE YOU DO NOT USE THE CAT CANNON AT THIS POINT. Continue spamming Ramen, but stop spawning the previous cats you have been spawning. Send in Manic Flying every 2 or 3 Ramen Cats, as well as an occasional Manic Macho Legs. When Awakened Bahamut is back, wait until the boss completes her attack, then send him in. He should be able to kill the remaining Gories. When the boss is about to attack, use the Cat Cannon to interrupt it. At this point, it does not matter if Awakened Bahamut dies. Spam your Lions, Fishman, and Hyper Mr. to get rid of the Sleipnir, and rush the boss to her death. If Clionel hasn't died by the time the three Angelic Gories come in, you may as well call it a loss.

Ending: Continue spamming Ramen and Manic Flying Cat to kill the remaining Gories. The 3rd Sleipnir can be handled by Awakened Bahamut, though timing is necessary as the Gories can still be alive. He can also be used to get rid of the Gories. If he dies, Ramen can still kill the Sleipnirs while Manic Flying can get rid of Gories if they still spawn. Rush the base and win!

Strategy 3[]

Lineup: Art History, Manic Macho Legs 30, Fishman Cat 30, Manic Lion Cat 20, Awakened Bahamut Cat 30

Cannon: Default Cat Cannon


  • The open slots are for useful Combos and a reliable Area Attacker that can sneak into Clionel's blind spot. Some options include Paris Cat, Crazed Bird Cat, or Ubers such as Kasa Jizo. Don't use cats with slow movement speed as it is almost impossible for them to get into Clionel's blind spot.
  • If you don't have Michelangelo, put Awakened Bahamut in your first row and Ramen in the second for more convenient deployment, and use the 4 first row slots for some Combos, especially a "Resistant" Effect UP Combo.

Opening: Like the other strategies on this page, start by sending out a Manic Lion as soon as you can, leveling up the Worker Cat, and sending out another. This timing allows for both Manic Lions to enter the blind spot of the boss, to keep her near the enemy base while dealing some minor damage, and eliminate the early Trolly Bloggers. Continue leveling up during this time, and save your Cat Cannon. When Angelic Sleipnir spawns, the Lions will die shortly after. When the leading Trolly Blogger reaches 1/4 - 1/3 from the enemy base, send out Manic Macho Legs. He will eliminate a dozen or so Trolly Bloggers and stall the Sleipnir long enough for the first Angelic Gory to spawn. Let him kill the Manic Macho Legs, for he has done its job.

Midgame: Let the Gory approach the base, and when it gets close enough, send out a Ramen, Manic Lion, and A. Bahamut. Continue spamming Ramens and Manic Lions to chip away at the Sleipnir. Meanwhile, focus on the approaching boss and use your Cat Cannon to interrupt her attack, the later in her animation the better. Depending on your luck with the Trolly Blogger knockbacks, your A. Bahamut should be alive and attacking the boss at this point. If not, that's ok, but it lowers your chances of success as this is the point where you deal more than 75% of your damage to the boss, or even kill her! Don't be discouraged if your Bahamut died, it's just bad luck. Regardless of your Bahamut's state, continue spamming Ramens, Lions, and now Fishmen and your attacker, being somewhat conscious of your money and timing so your damage dealers don't die from the boss' attacks. Your goal is to knockback Clionel at least twice.

Endgame: When your Bahamut recharges, take note of where the next Sleipnir is situated, so that if you were to spawn your Bahamut, he would be able to safely enter the pocket. If not, have faith in your attackers to at least knock her back once. When it is safe for your Bahamut, send him, and use your Cat Cannon to ensure he doesn't get hit by a boss attack. If all had gone smooth enough in the midgame, it should only take a few hits from Bahamut to kill the boss. From there it should hopefully be smooth sailing: finish off any remaining enemies and take out the base!

Strategy 4 (1 Cycle)[]

Lineup: Deathrock, Biohazard, Bony Bone, Ramen Cat 40, Manic Macho Legs, Manic Lion Cat 30, Delivery Cat 30, Maglev Cat 30, Cat's Gift 24+, Awakened Bahamut Cat 30

Cannon: Default Cat Cannon

Notes: Maglev Cat is replaceable, but is still recommended for consistency.

Battle: There is a very specific order in which to send out units. Start out immediately with Maglev and a Wallet upgrade as soon as possible. Cruel Angel Clionel will spawn, but she won't hit Maglev. Trolly Bloggers will start to appear, but they are not a problem because of Maglev's rebound mechanic. Maglev will constantly be knocked back by the Trolly Bloggers and in turn will easily kill them, giving you a huge cash boost. Send out another Maglev as soon as possible. Upgrade your Worker Cat all the way to Level 7, then stop. Both Maglevs will die, and Trolly Blogger, Angelic Sleipnir and Cruel Angel Clionel will all start making their way to your base. Right before the Trolly Bloggers start damaging your base, send out Maglev to continuously knockback and kill the Trolly Bloggers. DO NOT USE YOUR CAT CANNON YET.

Now, Angelic Gory should be arriving. Right before he attacks the Cat base, send out 1 Ramen and 1 Manic Macho Legs. When the Trolly Bloggers are clear, spawn Awakened Bahamut to take off a chunk of Angelic Gory's health. Now it's time to start spamming Ramen. You don't want Trolly Blogger to knockback Ramen too much, otherwise Bahamut could get hit. To prevent this, send out Maglev at the right time so Angelic Gory can't get any hits on Ramen. Manic Macho Legs should clear the Trolly Bloggers again, and Bahamut will finish off Angelic Gory. Once he dies, start spamming Manic Lions. Now, there will be units in Clionel's range and she will do her first attack. Use the Cat Cannon to intercept it, and if luck is on your side, Sleipnir will die to A. Bahamut, which should also be in Clionel's blind spot. During this time, do not mindlessly spam Manic Lion, Cat's Gift and Delivery Cat. Instead, time them all to save money and accumulate more damage. They should be relatively easy to time, since they all have decent speed. If Cat's Gift freezes enough, Clionel will be absolutely massacred, and so will the next Angelic Sleipnir, as you have a huge Manic Lion stack with Bahamut still alive. With all your units out, you destroy the base and win.

Fight with Sleipnir: With Clionel Cannoned, the cycle should be perfect. Sleipnir should knock back Bahamut just as Clionel attacks. Bahamut's hitbox will disappear, so he won't die to Clionel. An unfortunate way to go is if Sleipnir is too far from Clionel and he can kill Bahamut, resulting in Clionel not dying in time. But that is just luck of the draw.
