Jason keeps his new suit and identity for the rest of his tenure as a "Challenger of the Unknown", only to discard it on his return to New Earth and revert to his "Red Hood" street clothing.

At the start of Countdown, Jason Todd resumes the persona of the Red Hood and rescues a woman from Duela Dent (Two-Face's daughter).

Jason seems to have a romantic interest in Donna, and is shown to be visibly disgruntled when her old boyfriend, Kyle Rayner, joins their group as they take their tour to the 52 Earths which comprise the Multiverse.

A teaser image released to promote Countdown showed a figure resembling Red Robin among assembled heroes in poses symbolic of their roles in the series.

After a series of contradictory statements about this figure, executive editor Dan DiDio firmly stated in the July 2007 DC Nation column that the figure is Jason Todd; Todd, a major player in Countdown, has gone under the aliases "Red Hood" and "Robin".

[2] The Red Robin costume, originally designed by Alex Ross for the 1996 Kingdom Come limited series and worn by Dick Grayson, is seen in Countdown to Final Crisis #16 in the Earth-51 Batman's base of operations.

During a battle with a group of Monarch's soldiers, Earth-51 Batman is killed by the Ultraman of Earth-3[broken anchor], deeply affecting Jason.

In his grief, Jason murders an alternate version of the Joker who mocks his loss, vacating alongside Donna, Ray, and Kyle to the planet Apokolips before Earth-51's destruction.

When the Morticoccus virus is released from Karate Kid's body, Jason is forcibly brought back to the group by Kyle, much to his dismay.

He has come into possession of the Red Robin costume worn by Jason Todd, and uses it as part of a campaign of psychological warfare against Tim Drake.

Alfred Pennyworth has slightly altered the costume while mending it after the uniform sustained significant damage after Tim's confrontation with Ra's al Ghul.

Red Robin eventually rejoined the Teen Titans and took over as the team's leader after Wonder Girl stepped down.

This version of Red Robin is the leader of the Teen Tyrants, a group of young supervillains from an alternate reality where all of the world's heroes are evil.
