Is the easter bunny a biblical figure?

No but the eggs are Biblical.

Legend tells us that Simon of Cyrene, the man who helped Jesus carry his cross up to Calvary, was an egg merchant. Passing by on his way to market, Simon is stopped by Roman soldiers and ordered to help Jesus carry his cross to Calvary. Three days later, Simon rejoices when he sees that not only has Jesus risen from the dead but his eggs have been transformed into a colorful new gift from Jesus-the first Easter eggs!
