weeeell even sooo... there are books of other Henry hares, but they usually have things like Henry Hare and the storm, or Henry Hare and the carrots...
but luckily, I should be able to play around because technically each title is Henry Hare by llobu cerval
at least that's what a lawyer friend said. I can always enlarge the official title if it comes to legal problem, since it'll be clear that it is mine.
At least the comic itself, now the character is kinda different. yeah sure his name is Henry Hare, but in actuallity, his full name is Henry Von Spots Hare the I (and his original not pun name is Zhang Ming). and using all his unique features, face spots, palette, and outfit, I can always claim as my own character.
edit: also I didn't know until months later, I actually had an aunt also discovering and asking the same thing.
