Data-Riku is a boss who is fought in Kingdom Hearts coded and Kingdom Hearts Re:coded. A stronger bugged form of him appears on the 100th floor of the Avatar Sector in the Avatar Menu of Kingdom Hearts Re:coded.

Strategy

First phase

His first move is a forward thrust, so a simple dodge roll is all that is needed to avoid it. After that he is pretty easy. He only has a small selection of moves which he doesn't use in quick succession. He has a Dark Shield much like the one from Kingdom Hearts 358/2 Days which also reacts the same way if you try to attack the shield. You can either heal while his shield is up, or get behind him and attack. Keep watching his pattern, use dodge roll, and it should be easy to beat him.

Second phase

Riku now has two more attacks to use in the second round. He teleports above you and slams his Soul Eater below, sending several types of Bug Blox outwards to damage you. Use the same strategy as before, blocking then attacking. If he teleports into the middle of the air, quickly Dodge Roll away, or try and jump over the Blox, but this requires great timing.

Third phase

In this round, Data-Riku stops holding anything back and his stats improve. His strongest move is now used against you, Dark Aura. Much in the same way it was used in Kingdom Hearts and Kingdom Hearts: Chain of Memories he charges around the screen teleporting using his dark powers finishing with a slam which sends out a pulse of dark energy. This move is best Dodged since it's hard to tell where he will emerge next. (This could be avoided with the ability round block) So avoid it with Dodge roll and jump for the finishing blow. He can also fire a Dark Firaga, which can be blocked easily. The rest of the moves are the same but pack an extra punch so watch out.

Second Battle

While debugging Data-Riku, a portal opens to a facsimile of the Chapel, where the Bugs have taken Data-Riku's form. This Data-Riku follows the same pattern as the Third phase, but he has an extra bar of health.
