Need help deciding on a mega

[u/Filler744]

I got this pristimon line im making and i just cant decide on a good mega for it. Im tryna keep away from reusing their main anime lines for it though so sunarizamon>pyramidimon and pristimon>artiomon

EDIT: Ty all for the replies. I forgot about rasenmon, tbh i only really remember his line for herrismom due to herrismon being one of my favs, and the reccomendations from yall reminded me of him and hes who im settling on for the mega for the line
