Omega Trinity

 Omega Trinity (オメガトリニティ) are weapons that can be used by Axel in Kingdom Hearts 358/2 Days. It can be upgraded to Omega Trinity+.

This weapon's name may be a reference to his friendship with Xion and Roxas, similar to Sora's Trinity Limit referencing himself, Donald and Goofy. It also could connotate to the three spikes on the chakrams.

Design
An Omega Trinity chakram's main wheel is quite a bit smaller than those on most of Axel's other chakrams. It is black on the outer edge and gold on the inner edge. This type of chakram sports three enormous, red spikes shaped like the spikes on the Nobody ligil around the edges (the fact that there are three likely referencing the "Trinity" part of the name), and three much shorter, black spikes in between each large one. The handle is three-pronged, again unlike most of Axel's other chakrams, which usually have a four-pronged handle.
