Tom Dubius

Tom Dubius is a character from the MegaMan Star Force series. He is able to EM wave change to become cygnus Wing.

MegaMan Star Force
He is first seen in the game crash landing at Vista Point while testing his flying machine. He appears at AMAKEN as an assistant to Aaron Boreal. Aaron asks him to form a Brother Band with him but Tom is hesitant. He is then visited by Cygnus who inquires about Tom's past, and reveals that he didn't have many friends in school so all he focused on was his inventions. One day a man he was working with asked to form a Brother Band with him, an offer which Tom eagerly accepted. However his coworker only formed a Brother Band with him to steal his inventions, causing him to be unable to trust others. Cygnus tricks Tom into thinking that Aaron was stealing his invention by showing him that his flying "Flappack" was in Aaron's lab. Enraged, Tom EM Wave Changes with Cygnus and becomes Cygnus Wing, and attempts to kill visitors in a Space Simulation. Geo and Omega-Xis fight and defeat him but Tom would not defuse from Cygnus because of his distrust. He tells Aaron that if he truly trusted him, he would take his helmet off because he filled the room up with air earlier. Aaron takes off his helmet, and true to Tom's word there is air in the smulation. Touched by the act of trust, Tom defuses from Cygnus and returns to his job as Aaron's assistant.

Later, they were celebrating the completion of a new invention when Aaron announced that they were going to have a party. Tom says that it would be a bad idea as Aaron would gain a ton of weight. Aaron is iinsulted and declares that he'll eat as much as he wanted. Tom said that the reason he was concerned was because he was his Brother, implying that they formed a Brother Band.

Tom appears in MegaMan Star Force 3 as a minor character, and is revealed to be working at WAXA. He now has Cygnus as his Wizard, and can be fought as Cygnus Wing as an optional boss.

Shooting Star Rockman anime
Tom's story doesn't veer off to far from the game. He was betrayed in the past and Geo finds him when he crash lands with his Flappack. However, Cygnus takes over his mind as opposed to the games where he willingly transforms to take revenge. He tries to send a sattelite at AMAKEN but MegaMan stops him. However Cygnus escapes with Tom's body. Tom is later freed from Cygnus' control when MegaMan decimates Cygnus with Atomic Blazer.

Tom then returns to his job at AMAKEN and attempts to make up for what he did by inventing something. One of his inventions is an incomplete Viral Machine, which is supposed to lure viruses to it and delete them, but the deletion function was not complete. This resulted in havoc as Cancer Bubble exploits this to assemble a horde of viruses far too huge for MegaMan to take on. Eventually, when the machine is destroyed and the viruses dissipate, Tom takes responsibility for the creation of the device, and is later enlisted to invent new tools for the Satella Police. At the end of the series he develops the Star Carrier, which not only assists MegaMan and Harp Note, but lives on into Ryuusei no Rockman Tribe where everyone has one.

In Ryuusei no Rockman Tribe, Tom even develops an "Utagai Area", where people can use their Star Carriers to materialize objects. This comes into play a few times in the anime when the portal to Mu opens, allowing for EM viruses to materialize.
