 * Natural Durability: Jay has been shown to have a great amount of natural durability. Able to last almost thirty minutes against Blackjack without a drop of blood being spilled from either opponent. He is able to withstand attacks from gods and even the God like version of Gothic. Though his Durability does have it's weaknesses as he cannot take every hit and can be taken down with the right amount of damage.
 * Natural Speed: Jay's speed is his most obvious attribute able to block and dodge attacks at the speed of sound. When fighting this attribute comes in handy as he is known to dodge opponent's attacks without much thought. But even he can get tired, landing a hit on him can be quite easy if caught of gaurd.
