Gabriel differs from Doge Dark by normally having lower damage than it, but in exchange, Gabriel also gains area attack, shorter range, more health and much faster movement speed, being able to take down stacks of cats easily.
Like mostothervariants of Doge, if this enemy is sent out rapidly, he can be very annoying. Take advantage of Gabriel's 10 knockbacks to gain back ground control just as quickly as you may lose it.
You can use any high damaging or high dps cat like Ramen Cat, Jameira Cat etc.
Keep in mind that Gabriel has 80 range, shorter even than Li'l Tank Cat. This means you cannot efficiently stall it forever, so it is best not to stall him too close to base.
*In each stage, there is strength magnification, the value of health and attack power varies due to this value.
*Time between attacks is the time of the attack from the motion end until the next attack motion start
Trivia
If spawned with a boss shockwave, Gabriel is fast enough to hitbox clip through cats and hit the back lines. In particular, Gabriel can reliably snipe stacks of cats that are attacking the base from 350-400 pixels away. This can be prevented by firing the default or Slow BeamCat Cannon immediately(though Iron Wall and Thunderbolt can also do this, if timed more precisley.) Other speedy enemies, such as Assassin Bear, can also do this.
