Boba Fett is nothing, and I mean NOTHING compared to General Grievous. Grievous, before he had his lightsabers, killed Jedi with blasters, so you can argue his blaster skill rivals Boba's. (Well, it begins to, Boba Fett is exceptional)
But General Grievous with his four lightsabers would annihilate Boba
Whoever thinks Boba is gonna lose is a complete moron. I mean come on, get your info from another source rather then the bloody cartoon. Sure Grievous is a skilled with the sabers but Boba is hugely skilled with a large number of effective gadgets. I like Grievous and all but I just cant picture him winning this one.
GO BOBA FETT! 💃
