So, how do the ability work and why they work so selectively? Don't send me to the Search, it doesn't work for me. Neither can I read several hundreds or thousand of pages. My main questions, come from other users' replies. 1. When it came for the StarScream's scar, one person "told" me, that "wounds remain scars". But we all know, how badly has Megatron beaten him up. And soon he is all right. Then, why didn't he manage to restore after Arcee's attack? Speculation: he didn't have enough Energon or medical care to deal with. But will his scar dissapear soon? If it hasn't already. 2. Bumblebee's T-Cog. A body organ. One wrote about the possibility, that Ratchet put his own t- cog in Bee- bot. But we saw StarScream shooting at it, and he hit. If Bee's t- cog was damaged, how was it restored? Did this part start to restore after putting inside Bee's body, or did Ratchet need to repair it before giving to Bumblebee? 3. Body parts. Do Decepticons have something in reserve? So, why has KnockOut replaced StarScream's arm, but hasn't done the same to BreakDown eye? Beacuse they didn't want or couldn't? Actually, I had been thinking, that BD has his eye replaced, but was it a kind of bandage? Here. When StarScream lost his arm, KnockOut tries to convince him to accept another one, but its weaponry was more complicated. Should there be any problem while transformation, caused by this additional missiles? And how does StarScream restore his missles? Grows them up? Maybe someone else has any questions, which suit this thread?
