Though weak initially, each encounter with Baron Seal is more difficult than the last when his stats begin to skyrocket. He attacks rapidly and can freeze and/or weaken any units that survive his attacks. However, he moves quite slowly. He also has 320 range, making most melee attackers useless at higher magnifications where tanking becomes less and less possible, as he will just tear through them in seconds, wasting your money.
The top-secret technology of the Ancient Laboratory allowed Goma-sama to be reborn as a Super-Lifeform via genome-remodeling. Requires maximum caution, with strikes that both lower attack power and stop movement. Becomes more ferocious with each battle.
The word Goma in his Japanese name, Huge Goma, means "sesame", but it also references the spotted seal's Japanese name, that being gomafuazarashi, The first two syllables being goma references the sesame-like spots on their backs, which can also be seen on Baron Seal.
According to J.J. Jackrabbit's Japanese description, B.B.Bunny was set to become the first RedColossus but switched places with Sir Seal partway through, leading to an incomplete J.J. Jackrabbit and the creation of Baron Seal.
