Srimad Bhagavatam 7.10.39

7.10.39

एन: पूर्वकृतं यत् तद् राजान: कृष्णवैरिण: । जहुस्तेऽन्ते तदात्मान: कीट: पेशस्कृतो यथा ॥ ३९ ॥

enah purva-krtam yat tad rajanah krsna-vairinah jahus te ’nte tad-atmanah kitah pesaskrto yatha

enah
this sinful activity (of blaspheming the Supreme Lord)
purva-krtam
executed in previous births
yat
which
tat
that
rajanah
kings
krsna-vairinah
always acting as enemies of Krsna
jahuh
gave up
te
all of them
ante
at the time of death
tat-atmanah
attaining the same spiritual body and form
kitah
a worm
pesaskrtah
(captured by) a black drone
yatha
just like.

Not only Sisupala and Dantavakra but also many, many other kings who acted as enemies of Krsna attained salvation at the time of death. Because they thought of the Lord, they received spiritual bodies and forms the same as His, just as worms captured by a black drone obtain the same type of body as the drone.
