Creating the Splinter Bomb

Reunion with Bobbi Morse
- "I call them Splinter Bombs. Has a nice ring to it, doesn't it?"
"Is there any way for me to get my hands on a Splinter Bomb? Those really are a thing of beauty."
"Unfortunately, I shipped them all out yesterday. Plus I can't take all the credit. Original specs came from HYDRA technology way back when."

Following the attack on the United Nations Headquarters, Mori was visited by Bobbi Morse at his home in Okinawa. Upon meeting her, he commented on her change of hair color, from black to blonde and questioned her loyalties, but listened as she reassured him and convinced him to share information.
Mori attempted to kill Morse when he was informed that she had been working undercover for S.H.I.E.L.D., but she was able to defend herself and knock him to the ground while Melinda May and Lance Hunter shot and killed his guards who came to defend him. While on the ground, Mori tried yet again to take Morse out while she was having a conversation with Hunter by raising his gun silently, however, the pair both shot Mori dead before he could fire and continued their argument.
- Expert Engineer: Mori created the Splinter Bomb for HYDRA using technology developed from the study of the Obelisk and recycling an old design made by Vincent Beckers.
- His surname "Mori" means "forest" in Japanese.
