Square-Enix's time-traveling RPG Chrono Trigger has a knack for turning up where it wouldn't normally belong when it comes to fan creations, so it's not too surprising to see the property mixed together with Futurama.  Unlike a lot of similar fan art creations that mix properties together, this mesh created by Nina Matsumoto actually makes a lot of sense.  Of course Bender would fill in for Robo.  It's natural that the Hypnotoad will take over for Frog.  However, casting hit-first-and-ask-questions-later Leela as cavegirl Ayla is a brilliant choice, as is setting easy-going party girl Amy Wong as tomboy princess Marle.  Professor Farnsworth as Lucca works in the context of both of them being inventors.  Fry as Crono, however, seems to be giving Fry too much credit in the intelligence department.  They're both key protagonists and have spiked hair though, so it works.  Absent from the lineup is Magus, so of course I've been wondering who would best fit that role from the Futurama cast.   Considering that Magus begins as an enemy and later becomes a tolerated ally under pressing circumstances, I'd say that the choice is clear: Dr. Ogden Wernstrom.  Then there's the extended cast of Chrono Trigger to consider.  How about Amy's father Leo Wong as King Guardia XXXIII?  A pair of Nibblonians as Masa and Mune?  Dr. Zoidberg as Melichoir?  Mom as Azala?  Zapp Brannigan as Dalton?  The Big Brainspawn as Lavos?  The parallels go on and on.
