User blog comment:Drakan95/The Zodiac Killer vs Bill Cipher. Epic Rap Battles: Cartoons vs History. Season 2/@comment-27286780-20180403131153

This is one of your best works so far. Bill Cipher felt very in character. The lyrics were alot of fun and very memorable. This was very close, but the Ford line gave it to Ted Cruz.

as for the hint: I'm geussing Indominus rex vs Littlefoot.
