MegaMan Battle Network 5 Team ProtoMan
|Other appearances:||MegaMan NT Warrior|
Raika first shows up in the final rounds of the Red Sun Tournament. He spied on Lan and came before him to say that he was weak and would be defeated easily. Lan grows enraged and attempts to punch him but Raika easily brushes him off. Then after Lan defeats Nebula Navis in the Undernet, Raika declares that after watching him battle, there was a 99% chance of victory. However, he is still defeated by Lan and returns to Sharo after revealing that the reason he came was to demonstrate Sharo's millitary power, which he failed to accomplish.
Raika joins Team ProtoMan.
Using a combination of quick thinking and his tactical NetNavi, SearchMan, few have ever come close to beating them. Disgusted by the fact that Japan’s Net Saviors rely on Synchro Chips and Cross Fusion to defeat their enemies, he continually insults Lan's and MegaMan's intelligence and inability to analyze battle situations.
The past is forgotten, however, when Laika returns in Rockman EXE Stream with a new SyncroChip (and a better attitude), completing the Cross Fusion trio and adding a new member to the chosen marked with the Crest of Duo.
Laika bids his comrades goodbye and returns to Sharo early on in Rockman EXE Beast, but returns a few episodes later.Template:BN-stub
