Bulkhead looks huge and menacing, but he's only the former. Once you get to know him, he has a gentle soul. He's afraid of hurting things smaller and more fragile than him, has helped him grow past that. He has a low tolerance for jerks and bullies, and is quite happy to let people like that stew in the trouble they've made for themselves, but his better impulses—or at least, needling from those around him—always sway him into helping in the end. He's friends with Young Autobot, Bubbles, Boomer, Carrie, & Shaak Ti.
