Some creatures have been in this game for quite a while but have yet to get a hybrid. Here are some hybrids I would give them.
I made this one a little while ago in a different topic but it still fits here
Thoughts?
Troodon and Aquilamimus are missing
Where’s Megalogaia and Dimodactylus?
What about Veloarhacos and Erlikogamma?
Never realized how many older creatures are in desperate need of a hybrid or superhybrid. Some are definitely older than others though… ahem alankylosaurus
Albertoceros looks terrifying…
Dimodactylus, Megalogaia, Erlikogamma
And some more
Troomodactylus
Just tested it and Alankylotitan, Albertoceros, and Compsolasmus all beat Testa. Even Megalopelta can beat it when on revenge.
Dakotanops
oh you spoke my mind about dakotanops 
Poor thing needs some love
Megalosuchus could use some attention
Majundaboa requires one it’s pretty good cause of its counter plus another snake would be cool 
Majundaboa is already a hybrid of Majundasuchus, so it can’t have a hybrid.
But it would be cool if erlikogamma and majundaboa make a legendary hybrid it will be quick as well as a counter attacker 
I like your idea for ophiacomimius
Thank you for using my struthiogaia concept
Full body of it
I saw an imagine of it and thought it looked nice. I really like it.
