The Slow Explosion

The Slow Explosion was a subtype of the Explosion regeneration caused by a Time Lord being unwilling to regenerate. In the Slow Explosion, a gentle golden glow of regeneration energy built up into a dramatic burst of energy. (PROSE: How to be a Time Lord)

An example of this was the Tenth Doctor's regeneration. After taking a fatal dose of radiation to save the life of Wilfred Mott, the Tenth Doctor spent some time traveling to see his former companions before eventually regenerating into the Eleventh Doctor within the TARDIS. The resulting explosion greatly damaged the TARDIS control room, (TV: The End of Time) leading to a change in the desktop theme after the craft was forced to crash land. (TV: The Eleventh Hour)

Similarly, the Twelfth Doctor, after being gravely wounded in battle against the Mondasian Cybermen, (TV: The Doctor Falls) spent some time resisting his regeneration before an encounter with the First Doctor before his own regeneration convinced him to go through with it. The regeneration was an explosion which caused great damage to the control room, leading to the newly regenerated Thirteenth Doctor falling out of the TARDIS door (TV: Twice Upon a Time) and falling to Earth. (TV: The Woman Who Fell to Earth) When the Doctor reunited with the TARDIS, she found that the craft had "redecorated". (TV: The Ghost Monument)
