SWAT Kats: The Radical Squadron/Heartwarming

• The ending of "Mutation City".
• "The Wrath Of Dark Kat" also has a few, including another instance of the immortal "Hey, what took ya so long?" line. Also this exchange, when Razor is about to make the Heroic Sacrifice by deactivating the nuke while it is falling to the ground.

T-Bone: "Any last wishes, buddy... just in case?"
Razor and the nuke fall through the clouds, disappearing from sight. Then we hear his voice over the commlink:
Razor: "Get Dark Kat."
And T-Bone does.
