My proposed Limit Break
[b]Limit Break: [i]Custom Skill: GranLeo[/i] -[/b] Jake's axe(s) melt into his skin, causing him to get covered in a bronze or gold-covered liquid metal. He transforms from a 6'1" human to a [url=http://static3.wikia.nocookie.net/__cb20130402185905/digimon/images/d/de/Leomon_b.jpg]7'6" humanoid lion[/url] with razor-sharp claws on large, hammer-like fists and an iron-hard tuft at the end of his tail that can be used as a powerful mace or morningstar. Jake's defenses and strength double, and his speed and jump increase significantly, making him a terrifying close combat enemy. Jake in this form can also use a powerful roar to shake/intimidate foes or to knock back weak enemies, and can use his claws to climb sheer inclines. In GranLeo form, he can walk normally, but when he needs to run really fast, he gets down on all fours to high speeds.

Jake can only maintain this form for a limited time, and at the end of the transformation, he becomes exhausted, barely able to stand up let alone fight. Also, while Jake remains in control all throughout the form, the strain leaves him with severe headaches and vertigo afterwards.
