Notes

"Rawr..."

• Sentinel Supreme was named by Boo after he posted his character model.[1]
• It's possible that he has not actually appeared twice, and that it's actually two different characters with similar body types, akin to Bumblebee, Wasp, and everyone else who looks like them. However, this was not his creator's intention.
