- -- H.R. Wells src
Harrison Wells of Earth-19 was contacted by Cisco Ramon and the Harrison Wells of Earth-2 to serve as a replacement Wells for the team at S.T.A.R. Labs, along with several other Wells across the multiverse. Earth-19 Wells was selected as the best candidate for the team, and was "vibed" across 18 dimensions by Cisco to be brought to Earth-1. When he arrived, Wells pretended to be evil but revealed that he was just joking, and introduced himself as "H.R.".
When a massive monster attacked Central City, it's revealed that HR isn't a genius like his counterparts. In actuality he was an Author on Earth-19, and the public image of his Earth's STAR Labs. However he was revealed to be a fraud and with the help of his partner, Randolf Morgan, HR came to Earth one, beliving he could start fresh. 
During the time where Iris's death at the hand of Savitar was coming, Iris and Joe went to hide on Earth-2, HR and the others were tricked by Savitar into revealing her location. Feeling guilty, HR tracked Savitar down with the armor shard they had and used his facial reconfiguration device to switch places with her, causing HR to die instead of Iris.
- Business Management: As the face of Earth 19's STAR lab, H.R. managed the business, while Randolf invented things. On Earth 1, H.R. attempted to turn STAR lab into a museum, but largely failed.
- Storytelling: H.R. is a writer, often recording all his experiences with Team Flash as resource material. As shown in the alternate future of 2024, he became a successful writer.
