Lumaca was a contestant in the Multiverse Tournament from Universe 10 who was most likely a Saiyan. He/She was set up to fight XXI (pronounced KSEE). This Saiyan obviously would have lost due to later seeing XXI beat Vegetto by teleporting him to a dimension similar to the Hyperbolic Time Chamber but reversed so only after about 20 seconds, 2 hours had actually passed outside of the dimension, at the tournament. Lumaca most likely left with the other participants of Universe 10 in the middle of the tournament. At the time XXI had not even arrived yet although since they had known Lumaca was not coming back they gave the victory to him. XXI is set up to fight #18 from Universe 14.
