I haven't drawn Titan and Allen (Decided to change WOlf's name so avoid most confusion) together. They are basically the same person, Titan (Red) was created from Wolf's nightmares as the type of person he didn't want to be, and for a while the two hated eachother as opposite forces.

Titan is the Wolf of Flames where as Allen is the Wolf of Water. Titan loves pain, fear, destruction, action, and coming out on top where as Wolf likes keeping people calm, comfy, he loves creating things and is more passive than not, yet despite being opposites in almost every way they still show they are rather alike.

Their powers and views are almost exacally the same. They both have a deep fear of eahother, Titan being Wolf's nightmare self and Wolf's hurricane mode being 10 times more dangerous than Titan is and they like messing with eachother every chance they get. Allen is the only one of the WOlfs that actually respects Titan, the others seeing him as an accedental creation and a trouble maker, and Titan really likes Wolf, just doesn't like his goody tw shoes outlook. Guess opposites attract and all that.
