Raika

Straight from the snow-covered lands up north, Lieutenant Raika (Laika in Japan) of Sharo’s Net Saviors and operator of SearchMan.EXE, joins up with Lan Hikari and Eugene Chaud in the fight against Dr. Regal and the Darkloids.

MegaMan Battle Network 4
Raika first shows up in the final rounds of the Red Sun Tournament. He spied on Lan and confronted 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 (with MegaMan gaining Search Soul) and returns to Sharo after revealing that the reason he came was to demonstrate Sharo's military power, which he failed to accomplish.

MegaMan Battle Network 5
Raika joins Team ProtoMan. He is the counterpart of Higsby, because SearchMan (as his name implies) can search Dark Panels, similar to NumberMan. He is about to help Team ProtoMan get through a wall blocking access to liberating the End area when he gets called, because a criminal Navi he was looking for was spotted. He and SearchMan corner the Navi, but a Nebula Navi disguised as MegaMan attacks SearchMan and causes Raika to battle Lan when they meet up again. After they reconcile, Raika and SearchMan help liberate End Area. He is then mind controlled by the SoulNet Comp and battles Lan and MegaMan, but is returned to normal after the SoulComp is defeated. He joins Team ProtoMan in infiltrating Nebula's base and returns to Sharo after the mission is successful.

MegaMan NT Warrior
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. During VideoMan.EXE's attack on a movie theater, Lan and MegaMan Cross Fuse to confront him. However, VideoMan proves too tricky an opponent for R-MegaMan and ends up defeating him. He is about to delete R MegaMan. Meanwhile, Raika outwitted all the viruses in the Dimensional Area and reaches the Generator. He jacks in SearchMan who proceeds to destroy the Generator and save MegaMan.

Rockman EXE Stream
The past is forgotten (although not by much), when Laika returns in Stream with a new Synchro Chip (and a slightly better attitude), completing the Cross Fusion trio and adding a new member to the chosen marked with the Crest of Duo. This is rather ironic, as Laika previously would have never even considered or relied on Cross Fusing in battle. He also seems to develop a love interest with Princess Pride.

Rockman EXE Beast and Beast+
Laika bids his comrades goodbye and returns to Sharo early on in Beast, but returns a few episodes later, getting sucked into the portal to Beyondard with Enzan, Netto, Dingo, and Meiru. In Beast+, he and SearchMan fight Phantom versions of Rockman, Blues and one other to become cache data.

Trivia

 * Even though Raika stresses following orders, he is often the character to find error in an order, suggest a better plan, and even disobey orders, which embarrasses him.


 * Raika is the only character when Cross Fused that can actually drop his main weapon, the Search Rifle, to pick up another weapon. This makes it easier and quicker to switch between weapons, but it also means he can lose the Search Rifle if he takes too much damage on the downside.


 * It's revealed in Stream that Raika is an excellent fencer. This is very much to his advantage, as upon losing his Search Rifle as R-SearchMan, his next weapon is often the Katana battle chip, which can end up dealing a lot of damage.
